While model uncertainty is acknowledged by most op-erators who make use of quantitative models, most of the discussion on thissubject has stayed at a qualitative level and a quantitative framework

explanation for the nonmonotonuous ts dependence of the decay curves. It is clear thatwith inreasing ts we reach larger θm for the same ǫp, which is reflected in more oscillations.

Thus, the op-erator appearing there is an isomorphism for all nearby V ’s.
